The powders of semi coke
are graphitized to provide test carbon content upsides of more than 95%. Semi
coke, a result of the compound business, is another fuel for impact furnace
infusion in China. Strong squanders got from metallurgical ventures represent a
huge danger to the climate. The use and removal of these strong squander are
significant worries on the planet. Semi-coke created in coal-based direct
decrease cycle of iron metal is a side-effect and its reasonable usage isn't
accessible up until now. To deal with it appropriately, the attributes of this
result were extensively examined. Progress of examination techniques was
utilized to show its mineral arrangements, petrography, and physical-synthetic
properties. The outcomes uncover that the semi-coke has bad wash ability. The
fixed carbon substance of semi-coke arrives at 76.11% and the gross calorific
worth is 28.10 MJ/kg, the two of which are like those of conventional sinter
coke breeze.
Applications
Basic coke items are for the
most part utilized in metallurgical businesses, for example, impact heater
ironmaking and projecting. Semi-coke can't be utilized in impact heater
creation. Notwithstanding, in ferroalloy, calcium carbide, manure, and
different businesses, Semi-coke can totally supplant general coke, and its quality
is superior to numerous public norms for metallurgical coke, foundry coke, and
ferroalloy uncommon coke. Consequently, Semi-coke is improving the nature of
downstream items. Saving energy has higher application esteem as far as
lessening creation costs and expanding yield. Simultaneously, Semi-coke
likewise has improved power in the terms of impact heater infusion, creation of
carbonized materials, and actuated carbon.
Creation Technology
The creation of Semi coke is
for the most part dependent on low-temperature dry refining, and the dry
refining temperature is by and large around 600 ℃.
Costs of semi-coke
Because of contrasts in crude materials and cycles, the market cost of
semi-coke is less when compared to the normal coke. Accepting 2006 for instance,
the market cost of semi-coke was approximately 300 yuan/ton, and the normal
cost of the least grade coke (10-25 mm) was likewise 760 yuan/ton. The
moderately less market value makes semi-coke items own large market combat. All
in all, contrasted with coke, semi-coke has a more extensive scope of
utilization, more grounded practicability, and minimal price. Accordingly, semi
coke is currently one of the favored materials for allow smelting.
Semi-coke
briquettes
Direct family utilization of natural crude coals for cooking and
warming with no air contamination control gadget has caused genuine indoor and
open-air climate issues by radiating particulate matter (PM) and vaporous
poisons. The investigation analyzes family emanation decrease by changing from
anthracite coals and natural bituminous to handled semi-coke briquettes. Two
normal ovens were utilized to test outflow qualities when consuming 20 crude
coal tests generally utilized in private warming exercises and 15 semi-coke
briquette tests which were produced using bituminous coals by mechanical
carbonization treatment.
Quality
In contrast to coke items, semi-coke
production has the upsides of low dampness, low phosphorus, low sulfur,
high fixed carbon, low debris content, high compound movement, high explicit
resistivity, and so on "three highs and four lows."
